摘要

介绍了TEA CO

激光器火花针紫外预电离与主放电之间的延迟时间对激光器输出电光转换效率影响的实验研究结果。通过改变放电回路中的感抗值

可以改变预电离与主放电之间的延迟时间。实验结果表明:当预电离与主放电的延迟时间在200~600 ns范围变化时

激光器输出的电光转换效率存在最佳点

在注入能量相同的情况下

单脉冲能量从24.0 J提高到45.6 J

激光器的电光转换效率从8％提高到15％。经过进一步的参数优化

该激光器的电光转换效率最高可以达到17％以上。

Abstract

This paper introduces to the experiment results of a impact of the delay time changes between spark pin UV preionization and main discharge on the optoelectronic conversion efficiency in a TEA CO

laser. By using different inductance values in a discharge circuit

the delay time can be changed. The results indicate that the optoelectronic conversion efficiency has an optimal point when delay time is changed from 200 to 600 ns. In the same injected energy the single pulse output is increased from 24.0 to 45.6 J and optoelectronic conversion efficiency from 8％ to 15％ respectively. The highest conversion efficiency reaches 17％ after further parameters optimization.
